Post-inflammatory hyperpigmentation (PIH), those dark marks or spots left behind after a pimple heals, can be even more aggravating and distressing than pimples themselves. PIH is discolouration of the skin that follows an inflammatory wound. It is the skin's natural response to inflammation.PIH can develop in all skin types, but it tends to be more severe and longer-lasting for people with medium to dark complexions. PIH affects both men and women equally.
But Why Do We Get PIH?
PIH develops when a wound or irritation, like a scrape, rash, or pimple, causes the skin to become inflamed. As the skin heals, it produces too much melanin. Melanin is the protein in the skin that gives the skin its colour. It's the excess melanin that darkens and discolours the skin.1 This discolouration remains even after the wound has completely healed.
Most people with acne have some degree of PIH. And it's not just the big blemishes that cause these spots: Hyperpigmentation can follow even relatively minor pimples and papules. Now that we know what is PIH and why do we get it let's move on to how to treat it.
